Di-(2-Propyl Heptyl) Phthalate





Di(2-Propyl Heptyl) phthalate is a phthalate ester plasticizer based

on isomeric C10 alcohols.


It offers flexible PVC compounders higher powder bulk density,

which can enhance extrusion rates and the lower efficiency and

lower density of this plasticizer are said to result in lower cost per

cubic meter.


Its weather resistance makes it a strong candidate for outdoor

applications.  DPHP boasts better UV stability than most

general-purpose plasticizers, making it especially suitable for

applications like roofing, geomembranes, or tarpaulins. Color

stability and aging performance are particularly good.


DPHP is often used as an alternative to diisodecyl phthalate

(DIDP) because only minor compound changes are needed to

adapt wire formulations for example to DPHP. It similarly matches

DIDP performance in automotive applications.
